Description
- 1. Field of the Invention
- The present invention relates to a high-speed shear for transversely cutting rolled strip. Specifically, the present invention relates to a flying shear with knife edges mounted on drums arranged opposite each other, wherein the knife edges can be accelerated to the feeding speed of the strip to be cut and the knife edges can be adjusted toward each other for carrying out a cut.
- 2. Description of the Related Art
- In the manufacture of hot-rolled wide strip, the endless rolling method is used more and more. The material used is produced by welding preliminary strips or in casting machines. However, hot-rolled wide strip is also manufactured by using a semi-endless rolling method in which the material used may have the length of several preliminary strips which may be stored intermediately on roller tables, roller-hearth furnaces or in coil boxes.
- After the hot-rolling procedure, the finished strip must be cut to the strip lengths corresponding to the required coil weights. The cut should be carried out in continuous operation, i.e., at rolling speed. Accordingly, the cut must be carried out at the speeds of trains for hot-rolling wide strip which are conventional today in the range of 5 m/sec. to 30 m/sec., preferably 10 m/sec. to 20 m/sec. The strip thicknesses are between 0.5 mm to 30 mm, preferably between 0.6 mm to 1.5 mm.
- Rotary shears or guillotine shears which are conventional in the art and serve to cut hot-rolled wide strip, are not designed for such high strip speeds. However, flying shears which are used following cold-rolling tandem trains operate only at strip speeds of about 6 m/sec.
- Therefore, it is the primary object of the present invention to further develop a flying shear for cutting hot-rolled wide strip in such a way that exact cuts can be carried out at strip speeds of up to 30 m/sec. and on strips having minimum strip thicknesses.
- In accordance with the present invention, the drums can be accelerated by means of at least one drive unit to a circumferential speed which corresponds to the speed of the strip to be cut and a separately controllable adjusting device is provided for at least one of the drums.
- At the high strip speeds mentioned above, it is no longer possible to economically carry out the conventional cutting procedures in which the knife drums are accelerated to strip speed for carrying out the cut and in which the knife drums must subsequently be decelerated again. Therefore, a significant feature of the present invention resides in controlling the acceleration of the knife drum to strip speed or the operation of the knife drums at strip speed separately from the cutting movement which is carried out perpendicularly to the strip.
- It is possible early enough to accelerate the knife drum to its circumferential speed or to the circumferential speed of the knives corresponding to the strip speed or to rotate the knife drum continuously with a circumferential speed which corresponds to the strip speed, so that the drive unit for the knife drum can be small because the required acceleration forces are not substantial. The adjustment of the knife drum for carrying out the cut is effected through a separate system which, because it is a separate system, can also be of simpler construction than in the conventional cutting devices.
- In accordance with an advantageous feature, at least one of the drums is mounted on links which are connected to the adjusting devices; on the other hand, at least one of the drums may be mounted by means of at least one linear guide and the adjusting device acts on the guide members thereof. The drums or the knives cutting the strip can rotate at strip speed and, as soon as a coil length corresponding to the desired coil weight has passed the shears, the links or the guide members of the linear guide can be adjusted to carry out the cut.
- Various drives can be used for carrying out the adjustment. However, it has been found useful to construct the adjusting devices as eccentric adjusting devices or to provide pressure medium cylinders as adjusting devices.
- An optimum cut is ensured if both drums arranged opposite each other are equipped with knives. The knife drums must be exactly synchronized. If one of the two drums is provided with an anvil, or if one of the two drums is equipped with a casing which is hardened in such a way that it can be used as an anvil, an area is created in which the strip can be cut and in which a less accurate synchronization of the two drums is sufficient.
- It is important that the circumferential speed of the drums can be synchronized with respect to the feeding speed of the strip. The synchronization should be carried out in such a way that the circumferential speed of the cutting edges of the knives or the surface speed of the anvil or of the drum casing coincide with the feeding speed of the strip.
- It is also important that the adjusting devices are synchronized, controlled and/or operated relative to the rotation of the drum in such a way that the adjusting movements are concluded when the knives pass through and the adjusting devices are moved back after the knives have passed through. Before the cut is to be carried out, the knives are accelerated sufficiently early to the feeding speed of the strip. For carrying out the cut, the knives merely have to be adjusted toward each other. The adjustment is carried out in such a way that the movement of the knives, or of the knife and the anvil or the drum casing, is concluded at the beginning of the cut and, after the cut has been effected, the drums are moved apart again before the drum has carried out another rotation and, thus, another cut.
- The synchronization of the drums relative to each other or relative to the adjusting devices can be effected through appropriate gear systems or through electric or electronic means. The adjusting distance of the drums can be compensated by articulated spindles arranged between the gear systems or the appropriate drives and the drums.
- In order to be able to vary the cuts, devices for axially displacing the drums are arranged parallel to the adjusting devices. The axial displacement of the drums can also be carried out during the cut.
- If knives are used which have a predetermined curvature, specified shapes of the strip beginning can be obtained which help in reliably transporting the strip to the reeling unit.
- The various features of novelty which characterize the invention are pointed out with particularity in the claims annexed to and forming a part of the disclosure. For a better understanding of the invention, its operating advantages, specific objects attained by its use, reference should be had to the drawing and descriptive matter in which there are illustrated and described preferred embodiments of the invention.
- In the drawing:
- FIG. 1 is a schematic illustration of a shear according to the present invention arranged in a train for hot-rolling wide strip, wherein one of the knife drums is guided in a linear guide means.
- FIG. 2 is a schematic illustration, on a larger scale, of a shear according to the present invention with knife drums mounted on links;
- FIG. 3 is a schematic illustration of a shear with knife drums mounted on links, wherein one of the drums is equipped with an anvil; and
- FIG. 4 is a schematic illustration of a drive of the shear according to the present invention for achieving the mechanical synchronization of the shear.
- FIG. 1 of the drawing shows the
last stand 7 of a train for hot-rolling wide strip in which theendless strip 2 is rolled to the desired dimensions. The rolling train is followed by adriver 3 and ashear 5 for cutting theendless strip 2 is provided between thedriver 3 and another driver 4. Theshear 5 is composed ofdrums driver 3 or from a pickup, not shown. - The
drum 7 guided in linear guide means 21 can be adjusted by means of adjustingdevices 8 separately from the rotary drive, not shown, of thedrum 7. Thedrum 6 has aknife 20, while thedrum 7 is provided with a specially hardened casing which acts as a counterknife. The strip is wound onto areel 9. After the cut has been carried out, the strip beginning is conducted to thereel 10 and is wound onto thereel 10, while the finished coil can be removed from thereel 9. - FIG. 2 of the drawing shows the
strip 2 anddrums 6′, 7′. Thedrums 6′, 7′ are mounted onlinks fulcrum device 8′ acts on the respectively other ends of thelinks 6′, 7′. The adjustingdevice 8′ is an eccentric drive whose eccentric adjustingmember 15 is connected through connectingmembers links member 15 is required for moving the free ends of thelinks drums 6′, 7′ to carry out the cut. - Knives18, 19 are mounted on the
drums 6′, 7′. Devices, not shown, are provided for synchronizing thedrums 6′, 7′ mechanically or electrically or electronically, so that theknives - FIG. 3 of the drawing shows
links 11′, 12′ which support thedrums 6″, 7″. The free ends of thelinks 11′, 12′ are connected toeccentric adjusting members eccentric adjusting members drums 6″, 7″. Instead of theeccentric adjusting members other adjusting devices 8, for example, piston/cylinder units, can be provided. - A
knife 20 is arranged on thedrum 6′, while ananvil 24 is mounted on thedrum 7″. In this case, the synchronization between thedrums 6″ and 7″ does not have to be as exact as, for example, in the case of thedrums 6′, 7′ according to FIG. 2, because theanvil 2 provides a large cutting area for theknife 20. - FIG. 4 of the drawing shows a
drive unit 25 which is connected to a principal groovedroller gear unit 26. The principal groovedroller gear unit 26 acts on a groovedroller gear unit 27 for thedrum 6 and on a groovedroller gear unit 28 for thedrum 7. The adjusting force for the eccentric adjustingmember 22 is derived from the grooved roller gear unit through agear unit 29, while the adjusting force for the eccentric adjustingmember 23 is transmitted from the groovedroller gear unit 28 through agear unit 30. - The
drums gear units gear units 26 to 30 between theeccentric adjusting members drums member 22 is used, thegear units drums joint shafts stationary gear units 26 to 28 and thedrums - The shear according the present invention is used for dividing an endless hot strip travelling at high speed into lengths which correspond to the desired coil weights. At speeds of the hot-rolled wide strip of up to 30 m/sec. and strip thicknesses as low as 0.5 mm, the endless strips can no longer be securely introduced or threaded into the trains for hot-rolling wide strip. For this reason, the stands are adjusted, for example, to a gap of about 1.5 mm and the strip beginning is rolled with this adjustment until the appropriate tension can be produced by the winding reel. The stands of the train can then be adjusted to 0.5 mm. As soon as the first strip portions with the desired final thickness have passed the shear, the shear is adjusted to carry out the cut. Similarly, before the end of the strip enters the rolling train, the roll gap is again adjusted to about 1.5 mm and the shear is adjusted to carry out the cut before the strip which has now a greater thickness passes the shear.
- The cutting system disclosed herein for use in connection with hot-rolled strip can analogously also be used in connection with cold strip leaving cold-rolling trains.
- The invention is not limited by the embodiments described above which are presented as examples only but can be modified in various ways within the scope of protection defined by the appended patent claims.
